Imagery is a widely spread technique in the sport sciences that entails the mental rehearsal of a given situation to improve an athlete's learning, performance and motivation. Two modalities of imagery are reported to tap into distinct brain structures, but sharing common components: kinesthetic and visual imagery. This study aimed to investigate the neural basis of those types of imagery with Activation Likelihood Estimation algorithm to perform a meta - analysis. A systematic search was used to retrieve only experimental studies with athletes or sportspersons. Altogether, nine studies were selected and an ALE meta - analysis was performed. Results indicated significant activation of the premotor, somatosensory cortex, supplementary motor areas, inferior and superior parietal lobule, caudate, cingulate and cerebellum in both imagery tasks. It was concluded that visual and kinesthetic imagery share similar neural networks which suggests that combined interventions are beneficial to athletes whereas separate use of those two modalities of imagery may seem less efficient from a neuropsychological approach.
表象是运动科学中广泛应用的技术，通过在心理上重复练习特定的情境来提高运动员的学习、表现和积极性。据报道，有两种表象模式可以利用不同的大脑结构，但也有共同的组成部分：动觉表象和视觉表象。本研究旨在使用激活似然估计算法来调查这些表象类型的神经基础，并进行荟萃分析。系统检索仅检索了针对运动员或体育人士的实验研究。总共选择了九项研究，并进行了 ALE 荟萃分析。结果表明，在两种表象任务中，运动前皮质、躯体感觉皮质、补充运动区、下顶叶和上顶叶、尾状核、扣带回和小脑都有显著的激活。结论认为，视觉表象和动觉表象共享相似的神经网络，这表明联合干预对运动员有益，而从神经心理学的角度来看，单独使用这两种表象模式的效果可能较差。
